No matter how hard it’s drilled into Rob that he’s nothing but a cocksucking slut, he still thinks very highly of himself. At Breederfuckers Dave subjects him to a session of thorough de-humanization turning the proud doctor into a lowly grovelling pet. Given a harsh dog training session a buttplug tail is inserted into his asshole, he’s collared and made to walk on all fours. As a special treat he’s presented with a thick hard cock to suck and the dominant men make him choke on it. Two dicks are inserted in his mouth and he’s given a mouthful of cum.
